Kids shoe size chart by foot length
Age is only a rough guide. Foot length is the better starting point for infants, toddlers, little kids, and youth sizes.

| 11.5 cm / 4.53 in | US 4C | UK 3 | EU 19 | 9-12 months | Infant / first walker |
| 12.5 cm / 4.92 in | US 5C | UK 4 | EU 20-21 | 12-18 months | Toddler |

| 25.0 cm / 9.84 in | US 7Y | UK 6 | EU 39-40 | 12+ years | Youth / adult crossover |
Kids shoe sizes repeat numbers across infant, child, and youth ranges. Keep C/Y labels visible to avoid choosing the wrong range.
Shoe width guide
Width matters when the length conversion looks right but the shoe still feels tight or unstable.
| Width | Common men's label | Common women's label | Fit sign | What to do |
|---|---|---|---|---|
| Narrow | B or N | AA-B | Feet slide forward less, but sides feel tight | Try standard width first only if brand runs wide |
| Standard / Medium | D or M | B or M | Most default shoe listings | Best starting point for conversion charts |
| Wide | 2E or W | D or W | Toes or forefoot feel compressed | Use wide width instead of sizing up only for width |
| Extra wide | 4E+ or XW | 2E+ or XW | Ball of foot spills over midsole | Prioritize brands with extended-width models |
Width labels vary by brand. If length is correct but the forefoot feels tight, a wide width is usually better than sizing up.

FAQ
Should I measure feet with socks?
Measure with the socks you plan to wear with the shoes, especially for boots or athletic shoes.
What if my feet are different sizes?
Use the longer foot for sizing and adjust fit with lacing, insoles, or width options if needed.
Is foot length the same as insole length?
No. Shoes usually need extra internal room beyond foot length for toe movement and comfort.
